7. The control method according to claim 6 , further comprising selecting the second original image data corresponding to a number of pieces of insufficient original image data from the second original image data stored in the external storage in a case where the first original image data and the first number of pieces of thumbnail image data are stored in the designated folder and the number of pieces of the first original image data stored in the designated folder is less than the specified number.

8. The control method according to claim 7 , wherein the second original image data corresponding to the number of pieces of insufficient original image data is selected based on an access date and time of access to the second original image data stored in the external storage.

9. The control method according to claim 7 , wherein the second original image data corresponding to the number of pieces of insufficient original image data is selected based on an evaluation value for the second original image data stored in the external storage.

10. The control method according to claim 6 , further comprising accepting a setting about a number of pages of the data for printing, wherein the number of pieces of image data for creating generating the data for printing is specified based on the accepted number of pages.

11. A storage medium storing a program for executing a control method to be executed in a communication apparatus configured to hold first original image data and thumbnail image data corresponding to second original image data, the second original image data corresponding to the thumbnail image data being held in an external storage capable of communicating with the communication apparatus, the control method comprising: specifying a number of items of image data for creating data for printing; designating a folder in the communication apparatus; in a case where the first original image data and a first number of pieces of thumbnail image data are stored in the designated folder and a number of pieces of the first original image data stored in the designated folder is less than the specified number, executing processing of creating the data for printing using the first original image data and the second original image data by acquiring, from the external storage, the second original image data corresponding to a second number of pieces of thumbnail image data, the second number being smaller than the first number; and in a case where the first original image data and the first number of pieces of thumbnail image data are stored in the designated folder and the number of pieces of the first original image data stored in the designated folder is greater than or equal to the specified number, executing the processing of creating the data for printing using the first original image data stored in the designated folder without using the second original image data stored in the external storage.
